大型方坯初轧辊耐磨合金堆焊获得成功,并于1988年3月23日通过了部级技术鉴定。堆焊的焊丝主要是高碳钢和合金钢焊丝,专用合金钢焊丝几乎没有生产,再加上合金锻钢初轧辊制造工艺复杂,初轧辊一直不能适应高产、优质、低耗开坯生产的需要。1984年以来,鞍钢机械制造公司、鞍钢大型轧钢厂、鞍钢第一初轧厂 Large square billet initial roll wear-resistant alloy surfacing success, and on March 23, 1988 passed ministerial technical appraisal. Surfacing welding wire is mainly high carbon steel and alloy steel wire, special alloy steel wire almost no production, coupled with alloy forging steel roll forming process complexity, the initial roll has been unable to meet the high yield, high quality, low consumption of open billet production needs . Since 1984, Anshan Iron and Steel Machinery Manufacturing Company, Anshan Iron and Steel rolling mill, Anshan Iron and Steel Company first rolling mill
